The device was developed by the Texas Department of Public Safety and was used to measure rainfall and wind speeds, the Houston Chronicle reports.
The study was conducted by Texas A&M University, the Texas Parks and Wildlife Department and the Texas Commission on Environmental Quality.
The results were published online on the journal Environmental Research Letters.
“In this study, a flood measuring system was used as a water reservoir for the purpose of gauging the water level in rivers and streams in the vicinity of the site,” the study said.
“The device was calibrated using a water pump to accurately measure water level.”
The study also showed that the device works well for measuring rainfall, and the researchers were able to measure a rainstorm in a city as high as 3 feet in a few hours.
“It is very encouraging to see that a device that can measure rainfall is effective and not harmful,” University of Texas at Austin Professor Brian L. Smith, who led the study, told The Chronicle.
“We found that the measurement of rainfall in a given period was comparable to an hourly rainfall measurement using a rain gauge.”
The device measures the pressure and temperature of the water in a stream, but it is not an accurate measure of the actual volume of water that was in the stream.
“A rain gauge measures the amount of water vapor in the air,” Smith said.
This information was used by the study authors to determine that a rainfall gauge works well.
“To estimate rainfall from a rain gauge, we used data from a network of rainfall gauges and from data from several sites throughout Texas, including a rain collection system in Austin,” the researchers wrote.
“Using this information, we calculated rainfall by using the average rainfall during the study period, the average rain rate during the same period, and a rainfall level for the same time period.
This method was able to estimate rainfall of a specific volume, about 0.5 cubic feet per second.”
This rainfall data also provided the scientists with information about how the water flow changed over time.
“Data from several water collection sites in the area showed that rainfall decreased over time due to increased evaporation from the ground,” the authors wrote.
A rain gauge also provided some information on how rainfall patterns changed over the past week.
“Over the past 48 hours, a small rainstorm occurred in Austin, Texas,” the scientists wrote.
The rainfall data was also used to determine whether rain gauges are accurate for gauging rainfall.
“Rain gauges can measure rain and wind but are not accurate for precipitation,” Smith told the Chronicle.
